Purchased a set of Moody Brother aerial gunner wings. I happened to be looking at them under a loop when I noticed this anomaly. They look like pin heads and are nearly impossible to see with the naked eye. Is it a repair to the catch on the back? They appear to almost be too far over when trying to line them up to the the catch on the reverse, if they were put there to anchor it.

Sometimes you can look TOO closely at a wing. This is probably some dirt in the die ( or a small imperfections) that caused this effect. You sometimes find "Bell" wings with all sorts of these little domed imperfections.
